at ml it will be understood that this pump operated by the motor in theusual way drawing the lubricant from the sump or hottom of the crank c:se or from a t: 21k to -which the oil is pumped, from the cran case. andumping into the svstou from which it returns to the crank case forfurther circulation llfllountecl upon the crank case 10 is a lubricationdevice adapted to receive the lubricant ttrom the pump a ncl screen itand distribute it to various parts of the motor. This device e in the"form of a casting 1"? which suitably connected to tie crank case andwhich has an inlet passage 18 a l h ])1ess-uz.'e outlet uisssge 1.9,alow press: e outlet p'z cssagc 2 1 and an overflow passes 21. The inletpas sage 18 connects 'witl Q a" 1 the outlet irom the pump 1th aboverei'errecl to, the high sure pa ssao'e 19 connects w th a PIX} li whichc: lubri :ant to tl e ma" mgs 12 of the motor cruel: sl sit, and ti 7 spre:

18 anti the outlet pass 1hr high the erenl-z case Wall so that th j'naes to which they are connectetlare located inside the 0 Mil; fuse.

The casting 17 is formed with two screen pockets 25 which contlnremovable screens place in th: pockets by caps or covers 27 cletachablysc cured by bolts 28. In each of the covers is a vent opening 2.) closedby a thumb valve 3?, whereby air may he released from the upper part oi.the strainer pocket as Will hereinafter appear.

The low r end 0 each oi the screens 26 has atube 31 which sliclebly fitsan opening: 352

in the bottom of the pocket-25 so that the inte fior 01 the screen maycommunicate through said tube 31 With atrensverse passage 318 in thelower part of he casting 17.

Mounted in the casting 17 preferably betWeen the strainer 3OClKGtS 25 isplug; valve elhaving vsriou. L therein as will hereinafter described.The valve is mounted 3 1: in the c sting, the lower encl' ofvvhich borecommunicates with the overflow passage 21 hereinshove described and asparticularly shown in Figs. 1 and 9-,

l t owmthe iulet 1 and the plug is inserted from abovethrongh anopeningf35olosed by a threaded sleeve 36 tl'11'oug h which the stem 3701the plug pered seat. There is handle ll connectedpartseonnectswith'one'of the screens 26, and

to the upper end of the valve stem 82 for turning the valve and a springplnn zr 42 mounted in the outer e115- of the handle 4 tions, the plungerlil operating in either p v 1. 7 two openings 43 in thecovers 2?, asshown particularly in Figs. 3 and 8.

By referring to Fig. 5 it will'be seen that the passage l8 communicateswith a ch amber 118' in the lower part of the castingand this chambermay be connected by a passage 218 ill the Valve 33 wlththe transversepassage 318 here,

inabove referredto. Intact th'e'valve 33 divides the passage 318into twopar I eh t hand part and a left-hand part, each. 4 which.

when the valve 33: is in the position shown in F1g,- 5 the chamberlltlcommunicates with.

the left-hand part of the passage Slhandl when'the valve is switchedtoits other e2;-

treme positonmr turned 90, the chamber 118 j is cut oil from theleit-hand part of the pas- 5 in the. castingg'll and extends downwar 20above referred to which connects with th I sage 318 and placed incommunicationwith the right-hand partthereot. Thus the lubrican-tfromthe pump 16 may be fed to-either of the two screens 26 and the otherscreen" can be completely out off from ,con'ini'unica- 7 tiontherewith'for cleaning.

There is an outlet llOtrom eachof the screenpockets 25, and a'pa-ssage219 in the valve 83- connects either one or the other of said outlets119, depending uponthe'position' of the valve,-with a high pressurechamber 319. This high pressure ohamberfil?) cored I l ly thereinand'connectswitlr the h1g I I u'e outlet- 19 of the device, shownparticularlyin Figs. 1- Sand 6.

There isanotheroutlet from the high pressure chamber 3l9-injdicated atlein Fig, 2 and 6, an d-thisontletis controlle l by a yield in-g. valvea soringrth d et the pressure at which said valve open I justableabutment 47- determining the pressure of the spring.

The valve 50 and its s ring 52 are ofcourse,

locatedin the chamber 121 and as w-ill appear from Figs. 1,' 2 andF thevalvestem 37 also passes through the upper part of the chamber 121' andthe spring 40 islocatedtherein, It. will be evidenhtheretore, thatwhatever leak age there maybe aroundlthe plug valve 33 will passin'tothe overflow passage 121 and drain to the crankcase and therewill be noappreciable] pressure above atmosphere in the chamber 121-so.;thatleakage along the valve stem 37 will be at ant'nnnnuin.

In order that one ofthe screen pockets may be drain-ed when the-otherone s n use the.

valve 83 is formed witha drainageg'roove 221 which is shown asextending, longitudinally of'the valve enough to register with boil thepassage 318 and the passage l19'andjw1thits lower end communicating;with-the Chitin her 121. This groove is particularly shown sent it' willbe seen threaded sleeve and a cap iii-Figs. 1. and 9',as well as inFigs. 5 and 6 I andit will be seen that when the left-handscreen pocketis in communication with the lubrication line by the passagesz2l8and219., asthe parts are shown in Figs, 5 andG the drainage groove221'opens communicationgbe an 1'] n'ht-hand passagefilS; rlghtehand;

outlet: 119, and the lowerpart "of. overflow chamber 121', so thatpractically all of the lubricant left lathe pocket 25W1ll drain into:

hit) I the crank case. This may be facilitated by opening the valve 30on top of the screen pocket, thus permitting air to enterat the topofthe pocket. Also, aftenthe right hand screen has been removed andcleaned and returned to the right-hand pocket, the" to place the rightvalve 38 may be turned hand screen pocket in 'theflubrication line andthe valve 30 may then be opened to per:

init air to escape from the screen pocket. As soon as lubricant appearsthrough the vent 29 the valve 30 will be closed and the righthand screenwill then be in full operation. The left-hand screen may then be removedfor cleaning and the operation repeated as often as desired withoutstopping the motor. In both of its extreme positions the valve 33 isretained against accidental. movement the plunger 42 above described.

While I have herein described in some detail a specific embodiment of myinvention, which I deem to be new and advantageous and may specificallyclaim, I do not desire it to be understood that my invention is limitedto the exact details of the construction, as it will be apparent thatchanges may be made therein without departing from the spirit or scopeof my invention.
